Flajnik wasn't the only one to get around when it comes to dating celebrities. His final choice, Courtney Robertson, apparently had a fling with Jesse Metcalfe (from Desperate Housewives and John Tucker Must Die) before she ever appeared on The Bachelor. According to her juicy memoir — I Didn't Come Here to Make Friends: Confessions of a Reality Show Villain — she's also dated Adrian Grenier and Gerard Butler and even had a steamy fling with the most recent Bachelor, Arie Luyendyk Jr.
